COMPOSITION OFMA'TTER FOR MORTAR.

SPECIFICATION forming part of Letters Patent No. 434,490, dated August19, 1890.

Application filed December 10, 1889. Serial No. 333,243. (No specimens!)of the invention, such as will enable othersskilled in the art to whichit appertains to make and use the same. r

Our invention relates to an improvement in plastering compounds, theobject being to provide a cheap plaster capable of quick and easyapplication to walls or other surfaces and one possessing greatdurability and adhesiveness; and it consists in certain wellknowningredients having affinity for one another, combined in suchproportions that a concrete mortar is produced which can be readilymixed and applied.

More specifically speaking, it consists of the following ingredients,mixed in substantially the proportions named: Coal-ash, five parts;sand, six parts; marble-dust, two parts; PIELStGP-OfiPfidlS, five parts;fine shorts, one part; sugar or. other saccharine matter, oneeighthpart. In addition to the parts mentioned a small proportion of gluesayonethirty-second part-may be used, and the whole is worked to the properconsistency by the use of water.

The ashes employed are such as are taken from stoves and furnacespossessing pyrites of iron, oxidized iron, slate, unconsumed bituminousmatter, magnesia, a weak alkali quality, and unconsumedbrimstone, eachof which has affinity for the other components of the composition. Theseashes are reduced to powder by any'practicable. and desirable method.After the ashes are reduced to powder the marble-dust, shorts,plaster-of-paris, and sugar are added and thoroughly mixed together witha hoe, shovel, or by other means. Water is then added in sufficientquantity to render the mass thinner than necessary to apply, and finallythe substance is brought to the proper consistency for application byadding sand.

To make the mortar set quickly or make it hard more plaster-of paris isused. The shorts or other glutinous matter from the cerealsas flour,bran, rye-flour, or oil-cake meal-act as a bind, and also by increasingthe quantity retards the setting of the plaster-of-paris and gives theworkman more time in which to apply it. The marble-dust settles next tothe lath and wood or wall and gives a firm compact concrete mass throughout. i

This mortar is easily applied,working freely under the tools. Thearticles used are com mon to all countries and easily obtained andcheaply prepared for use.

Having fully described our composition of matter for mortar, what weclaim as new, and desire to secure by Letters Patent, is-

A plastering compound consisting of ashes, sand, marble-dust,plaster-of-paris, shorts, and sugar or other saccharine matter,substantially as set forth.

In testimony whereof we have signed this specification in the presenceof two subscrib ing witnesses.
